State Estimation

State Estimation Analysis

ETAP State Estimation processes telemetry data such as power measurements to obtain an estimate of the magnitudes and phase angles of bus voltages in the actual power systems.
State Estimation

Using these values and the electrical model, the State Estimator examines the data for obvious data errors, determines those portions of the network which have sufficient telemetry to be observable, generates artificial measurements ("virtual" measurements) at locations where they are required for observability, complements with pseudo measurement and then computes the estimate of the system voltages and electrical power flows for the entire system.
